Subject: [PATCH] Better UID Calculation + Longer ObjectUID Column

Don't even bother using vector in the key calculation, the sqf ObjectUID
isn't as critical anymore. This method will be much faster.

Changed ObjectUID column to Varchar since with this key generation
method we can approach the BigINT ceiling much quicker than we used to.
